Title: High efficiency encoder of video signal
Inventor: NAKAGAWA YASUSHI
IPC: H04N19/00
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To improve encoding efficiency and to reduce the quantization distortion of a block including a boundary at the time of highly efficiently encoding the video signals of a letter box type. SOLUTION: Input analog video signals are A/D converted in an A/D converter 2, separated into luminance signals Y and color difference signals Cr and Cb in a Y/C separator 3, and stored in a frame memory 4. A letter box boundary detector 5 detects the boundary of a non-image part and an image part for respective frames by a line unit. In the case that the boundary is over the image processing unit (block) of video signal high efficiency encoding, an encoding object image control part 6 shifts the entire screen, replaces the non- image part positioned on the inner side of the image processing unit (block) including the boundary with the data of the adjacent image part and replaces the non-image part with specified uniform data. The encoding object image control part 6 reads the image signals of the image part from the frame memory 4 and supplies them to an encoder 7.

Title: Surface plate for optical apparatus
Inventor: MATSUMOTO YOSHIO
IPC: G02B7/00
Filed: 1993-05-25
Abstract: PURPOSE:To provide the surface plate which is light in weight and highly robust, is less thermally expanded and contracted and has high accuracy by using a carbon fiber reinforced composite material formed by impregnating high- elasticity carbon fibers with a thermosetting resin and molding these fibers. CONSTITUTION:An optical base bed body 1 is the carbon fiber reinforced composite material obtd. by laminating the carbon fibers having the minus coefft. of thermal expansion in the fiber direction of the fibers and the coefft. of thermal expansion as the carbon fiber composite in the surface direction is within a -1X10<-6> to 3X10<-6>/ deg.C range. The coefft. of thermal expansion of the matrix is plus and, therefore, the coefft. of thermal expansion in the fiber direction as the composite increases when the carbon fibers having the plus coefft. of thermal expansion in the fiber direction of the fibers is laminated. The expansion or contraction of the surface plate by a temp. change, then, increases and the surface plate does not meet the purposes any more. The precision measurement is made difficult by the influence of the expansion or contraction of the surface plate arising from a temp. change if the coefft. of thermal expansion as the carbon fiber reinforced composite material in the surface direction deviates from the range mentioned above. Such case is similarly undesirable.

Title: Image processing device
Inventor: YANAGIDA AKIKO
IPC: G16H10/60
Filed: 1995-06-12
Abstract: PURPOSE: To effectively emphasize a part changed by the lapse of time such as newly generated shade and shadow of a lesion and to improve diagnosing accuracy and diagnosing efficiency by producing an energy difference processing image between original images by at least two kinds of radiation rays transmitting the same object and performing inter-image arithmetic processing. CONSTITUTION: A soft image B0 is produced from a high energy image Hr and a low energy image L by applying simple weighted subtraction, and the image B0 is multiplied by a smoothing filter Fb1 which takes the average of masks of several picture elements. In such a case, a bone image Si is obtained by subtracting the soft image B0 to which smoothing processing is applied from the original image, however, it is convenient to use an image A in which two original images are weight-averaged compared with the one in the case that either the high energy image or low energy image is used as the original image judging from the standpoint to reduce a noise as many as possible. While, a soft image B1 is generated by subtracting the image S1 in which the bone image S1 is smoothed by a smoothing filter Fs1 from the weight-averaged image A.

Filed: 1979-11-09
Abstract: PURPOSE: To obtain a more compact and cheaper inked-ribbon feed mechanism by storing a plurality of ribbons in one case and actuating the feed mechanism of a desired ribbon by means of levers interlocked with printing hammers.  
     CONSTITUTION: With a solenoid not operated; when a lever 13, which is opposed to a lever 14, is turned and consequently the lever 14 is turned, a ratchet wheel 25 is rotated by one pitch through a ratchet 23, and this causes a printing ribbon 6 to be fed by one pitch through a belt 28 and a pulley 27. On the other hand, with the solenoid operated; when the lever 13, which is opposed to one end of a lever 17, is turned and consequently the lever 17 is turned, a ratchet wheel 32 is rotated by one pitch through a ratchet 30, and this causes a correcting ribbon 7 to be fed by one pitch through a belt 35 and a pulley 34. The ribbons 6 and 7 travel in parallel vertically. The solenoid is operated not at printing but at correcting to turn a case 4 so that the ribbon 7 faces to a platen.

Title: Steel bar and wire rod with superior cold forgeability
Inventor: MINAMI TOSHIHIRO
IPC: C22C38/00
Filed: 1977-11-30
Abstract: PURPOSE: To provide a steel material with superior cold forgeability for steel bars and wire rods, obtd. by adding Zr to a low carbon Al killed steel.  
     CONSTITUTION: Zr is added to a low carbon Al killed steel to make a steel contg. C<0.08%, Si<0.10%, Mn; 0.20W0.50%, Al; 0.02W0.06% and Z; 0.03W0.08%. The Zr added couples with C and N dissolved in the steel, precipitating carbonitride. The coupling with C lowers the strengthening action of C on the steel and lowers the strength. The coupling with N makes the steel unaged and gives superior characteristics as a wire rod or bar for cold forging. When the Zr content is below 0.03%, the effect is not obtd. enough. In case the content exceeds 0.08%, the effect of lowering the strength and hardness is shown, yet crack occuring limit compressiblity is made low, obstructing the cold forgeability.

Filed: 1981-09-11
Abstract: PURPOSE:To reduce considerably the capacity of an ROM and to improve a decoder, by using the quotient remainder of a primitive polynomial as the address information of the ROM and then comparing the output of the ROM with the quotient remainder of another polynomial. CONSTITUTION:A feedback register 5 divides a receiving data with a polynomial having a primitive root of a polynomial g1(x) of a BCH (Bose-Chaudhuri-Hocquenghem) code and delivers the quotient remainder. While a feedback register 6 divides the receiving data with the 2nd polynomial containing the factors other than those contained at least in the 1st polynomial among the factors of a grown polynomial g3(x) of the BCH code and delivers the quotient remainder. The quotient remainder, i.e., the output of the register 5 is used as an address  input for an ROM3. Then the coincidence is detected by a coincidence detecting  circuit 7 between the output of the ROM3 and the quotient remainder, i.e., the  output of the register 6.
